Linux/Unix & their associated command line stuff. The number of times it’s come in handy to be able to SSH into a machine that’s way over there and do stuff is immense. Sadly I waited till Uni to learn, and I wonder where I’d be now if I’d internalised these concepts by the age of 15.
Need to log something you’ve just done? Redirect the output into a file. Boom. No longer do you have to find the bit of software that does everything, you just need programs that do simple stuff you can repurpose*.
Reading FOLDOC a bit to get the history was handy too. Thinking of computers as CPUs attached to teletypewriters, with all that fancy graphics stuff as optional explains a lot of how current software ended up the way it is.
*Totally not advocating mainstream computing for every user end up like this, btw. (Linux still makes me cry on a regular basis) Just that being able to drop to a command line and chain together commands or write scripts is so powerful that it’s a game changer.

Majorly with you on this one. Piping in shell changed my life, and then piping in R (via Magrittr via dplyr) changed my life again.
